Multi-fluid Plasma Modelling
Contemporary plasma fusion experiments use significant power injection for plasma heating. The injected power selectively heats only part of the plasma, which then transfers its energy to the rest of the plasma through collisions. Continuous power injection gives rise to a dynamic equilibrium …

A study of reversed shear Alfvén eigenmodes in Alcator C-Mod with phase contrast imaging
… waves are a fundamental mode of magnetized plasma oscillation and may exist in tokamak plasmas as eigenmodes with a global structure and discrete frequencies. The inhomogeneity of the plasma profiles in conjunction with tokamak geometry tends to focus the Alfvén waves in regions of near …

Next Generation Algorithms for Magnetically Confined Fusion Reactor Simulations
… non-linear MHD (magnetohydrodynamics) plasma instabilities and disruption events. The objective is to model all reactor regions (plasma, quasi-vacuum, and containment vessel) within a single three-dimensional simulation on a Cartesian reference frame, diverging from traditional …

Oscillations and waves in anisotropic plasmas
… Vlasov-Maxwell equations describing anisotropic plasma oscillations and waves are studied using an operator theoretic approach. The model considered is one dimensional so that after velocity averages perpendicular to this direction. have been taken, the equations can be naturally grouped into one …

Bayesian modelling of nuclear fusion experiments
… given multiple heterogeneous data sets. Fusion plasmas are complex physical systems, in which charged particles are confined by the electromagnetic force. The physics parameters of the plasmas involve various independent measurements from sophisticated scientific instruments. Owing to the …

GPU-based, Microsecond Latency, Hecto-Channel MIMO Feedback Control of Magnetically Confined Plasmas
… tool in the research on magnetic confinement of plasmas for achieving controlled nuclear fusion. This thesis presents a novel plasma feedback control system that, for the first time, employs a Graphics Processing Unit (GPU) for microsecond-latency, real-time control computations. This novel …

Data-driven study of major disruption prediction and plasma instabilities across multiple tokamaks
… Along the way, scientists need to learn to avoid plasma disruptions: these sudden and unexpected plasma terminations still represent one of the key challenges for tokamak devices. Forecasting plasma instabilities and disruptions using first-principle models has been demonstrated to be extremely …
